Well there’s no reliable way to detect running in Node.js since every website could easily declare the same variables, yet, since there’s no window object in Node.js by default you can go the other way around and check whether you’re running inside a Browser.

Although Node.js is not a JavaScript framework, many of its basic modules are written in JavaScript, and developers can write new modules in JavaScript.

Here’s his presentationand a look at where the market of the Internet of Things is and how technologies like Node.js (JavaScript) and the Intel Edison are making it easier to create connected solutions.

The major topics include: – – * What is the Internet of Things – – * Where is IoT Today – – * 4 Parts of IoT (Collect, Communicate, Analyze, Act) – – * Why JavaScript is Good for IoT – – * How Node.js is Making a Dent in…

On one hand this might be the behavior you want, but it also dictates what variables the library user can use in the global scope.

The trick however, is that if we are assuming that your script is being loaded in the global scope (which it will be if it’s loaded via a script tag) a variable cannot be reserved in an outer closure, because the browser does not allow that.

Now remember in node, the object is an empty object, yet, the variable is still available.

So we can then fix underscore’s check by adding an extra check: – – With this, if someone declares in the global scope in the browser, it will be placed in the object, which will cause the test to fail, because , will be the same object as module.

Thus, the final test is: – – Note: While this now allows the variable to be used freely in the global scope, it is still possible to bypass this on the browser by creating a new closure and declaring within that, then loading the script within that closure.

Before we jump into HTTP timings, let’s take a look at some basic concepts: – – IP (Internet Protocol): IP is a network-layer protocol, deals with network addressing and routing.

An HTTP client initiates a request by establishing a TCP connection.

TCP Connection: Time it took to establish TCP connection between a source host and destination host.

To measure HTTP timings in Node.js, we need to subscribe to a specific request, response and socket events.

Here is a short code snippet how to do this in Node.js, this example focuses only to the timings: – – DNS Lookup only happens with domain names: – – TCP Connection happens immediately after the host is resolved: – – TLS handshake (SSL) happens only with https protocol: -…

The easy way to do is, put all your files including index.html or something with all resources such as CSS, JS etc. in a folder public or you can name it whatever you want and now you can use express js and just tell app to use the _dirname as…

we are creating express instance named app and we are giving the adress if the public directory to access all the resources.
